WIRE-HAT-FRAME MACHINE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed April 14,1906. Serial 311,695.

To all whom it may concern:

Be it known that 1, CHARLES W. STEvENs, a citizen of the United States,residing at East Orange, Essex county, New Jersey, have invented certainnew and useful Improvements in Wire-Hat-Frame Machines, of which thefollowing is a full, clear, and exact description.

My invention relates to wire hat frame machines.

One object of my invention is to provide a machine upon which wire hatframes of any form may be made more rapidly than on machines previouslyin use.

A second object is to provide means for readily releasing the completedframe.

A third object is to provide means for readily copying the shapes ofhats made from felt or other materials.

A fourth object is to provide means for copying a shape on a form fortransferral to other machines from which duplicate forms may be set up.

The invention consists in improvements, the principles of which areillustrated in the accompanying three sheets of drawings.

Figru'e 1 is a side elevation of a machine embodying all theimprovements of my invention. Fig. 2 is an enlarged view partially insection, showing parts of, the apparatus for forming a single hat. Fig.3 is a detail plan view of the cross bars for clamping the adjustableholding arms in place. Fig. 4 is a sectional detail view of the end ofone of the adjustable arms, showing anauxiliary tip. Fig. 5 is a viewsimilar to Fig. 2, but showing the upper part of the machine for copyinghat frames formed on the lower part and also for assisting in theformation of hats of unusual shape. Fig. 6 is a detail horizontalsectional view of the cross bars of the upper forming mechanism shown inFig. 5. Fig. 7 is a detail plan and sectional view of a collar forsupporting the arm-carrying brackets.

1 is the base, of suitable material, carrying an upright tube or hollowpost 2, preferably of metal. 3 is a collar rotatably supported on thepost 2 and having a limited vertical play. A series of brackets, such as4, are pivoted to collar 3 and have extensions 5 which carry sets ofpivoted arms. These arms are preferably formed in two sections 6 and 7,which telescope relative to one another and are guided relative to eachother by clips such as 8-8.

9 is a cross bar secured to and forming a part-of the bracket 4 at theupper end, and having a longitudinal centrally located slot similar tothe slot in the clamp bar 10. The arms are flat and extend between thecross bar 9 and the clamp bar 10.

11 is a thumb nut for clamping bar 10 toward bar 9 so as to hold thearms securely in position.

A second series of adjustable telescopic pivoted arms are carried by thebracket 4 on the opposite side to the arms composed of the parts 6 and7.

Each of the members of this second set of arms is composed of telescopicmembers 12 and 13 guided by clips 14 relative to each other.

15 is a cross bar somewhat similar to bar 9 and carried by and forming apart of the bracket 4.

16 is a clamp bar which may be forced toward bar 15 for the purpose ofclamping the arms by means of clamping devices 1717.

Each of the bars 9, 10, 15 and 16 are provided with longitudinal slotssuch as the slots 17. The upper ends of some of the arms carry auxiliarytips 18, as shown in Fig. 4.

19 is a clamp nut on the stud 20, for the purpose of clamping the tip 18to the arm member 7. v

Each arm member 7 is preferably provided with a perforation 20 so thatan auxiliary tip may be secured thereto. Each of the arms and theauxiliary tip members are provided with notches, as indicated at 21,facing outward and upward.

It will be seen from the description thus far that each of the arms maybe extended or made of the necessary length to bring the notched endinto the position necessary for holding the wire as desired. So also thearms may be swung on their pivots on the bracket for the purpose ofvarying the position of the end notch. In this way it is possible toadjust any one of the arms independently of all the other arms, itsimply being nec essary to loosen the clamps, such as 11 and 17,sufliciently to allow the armadjacent thereto to be adjusted. Of coursethe movement of any one of the arms between the bars 9 and 10 toward oraway from the axis of the supporting post 2 is limited by the positionof the adj acent arms. When this limitation prevents operation in thedesired manner, one of the arms between the ad jacent bars 15 and 16 maybe adjusted to meet the condition required.

22 is a collar connected to the bracket 4 by links 2S23 and verticallyheld between the two clamp rings 24 and 25.

The apparatus thus far described, so far as the actual formation of anyordinary hat is concerned, is complete, and, indeed, hats may be formedupon such mechanism. To more readily facilitate the removal of thecompleted frame from the machine, I prefer to provide mechanism forsimultaneously releasing all of the arms which support the wire of theframe. 26 is a rod vertically movable in post 2 and having secured to ita ring 27 by means of screws 28-28. These screws pass through verticalslots 2929 in the post 2 so that the rod 26 and the supporting ring 27may be moved upward from the position shown in Fig. 2. This upwardmovement carries the collar 3 and the lower ends of all the brackets4-4. Such upward movement of the collar 3 causes the upper ends of thebrackets to be moved toward the axis of the post by reason of theconnecting links 23-23. Such action instantly releases the wire frame(not shown) from the supporting arms.

Depression of the pedal 30, thereforefraises the rod 26 and will releasethe hat frame from the arms.

. 34 is a post carried by the base 1 and having a tele- -'scopingextension 35.

36 is a cross bar rotatable in a horizontal plane at the top ofextension 35 and supporting the hollow post or tube 37. I

38is a collar vertically movable on the post 37 and also rotatable andcarrying a series of pivoted brackets 39-39. These brackets haveextensions, such as 40, to which are pivoted a series of telescopic armsmade up of the portions 41 and 42.

4343 indicate guide clips for relatively positioning the two portions 41and 42 of the arms.

The outer end of the bracket 39 has formed as a part of it a cross bar44.

45 is a clamp bar secured to the bracket by bolt 46.

47-47 indicate clamping devices, by means of which the bars 44 and 45are drawn toward each other so as to clamp the arms which are locatedbetween them. Each of the bars 44 and 45 are provided with longitudinalslots, such as 47, so that the clamping devices may be movedlongitudinally to accommodate the necessary adjustment of the arms. Theend of each arm is notched, as at 48, and also preferably perforated, asat 49, similar to the arms heretofore described and for the samepurpose.

50 is a collar carried by the post 37 and connected to the brackets 3939by links 51-51 and vertically positioned between the clamp rings 52 and53.

54 is a ring.

55 indicates a screw which passes through the ring 54 and through avertical slot 56 in the post 37 and takes into the vertically movableplug 57. This plug 57 is connected by a wire 58 to the cross lever 59 atthe top, and is supplied with a cotter pin 60. Lever 59 is pivoted at 61and connected bya rod 62 to the rear end of lever 31 at the base, bymeans of a link 63 similar to link 33.

The arms of the upper set shown in Fig. 5 may be extended and adjustedsimilar to the'arms of the lower set and brought into play for providinga holding position for the Wire in the formation of hats of unusualshape. A great many hats which cannot be formed on the ordinary machinecan be formed by the use of one of these overhanging mechanisms. Bymeans of the connection to the lever 31, just described, the depressionof the pedal 30 releases all of the arms of the upper set at the sametime that it releases all of the arms of the lower set. By means ofthese oppositely positioned sets of arms, shown in Fig. 1, it ispossible to adjust one set to be the opposite or reverse of the other.In this way, for instance, let us suppose that the lower set is adjustedand the hat formed thereon. The upper set may then be brought into playand adjusted with its arms in corresponding positions. This upper setmay then be swung to one side and left in that form, so that afterwardsthe manufacturer can use it as a model to aid him to readjust the lowerset if it has been disarranged. A single standard hat may be ad justedon the lower set of arms. If then the upper set is brought into play, asort of mold may be formed by adjusting the arms of the upper set to theproper shape. This skeleton mold may then be removed from the machineand applied to another machine, so that a lower set on this secondmachine may be arranged for duplication of the original model. This isof particular advantage where a great many hats oi the same shapeare tobe made, in which case a number of machines would be in use. It will bereadily seen that the lower set of arms may be removed by simplyloosening the two clamp rings 24 and 25. Similarly the upper set may beremoved by taking off the clamp rings 52, 53 and 54. Both sets of armsmay be freely rotated about their axes for more readily reaching thedifferent parts of the mechanism in forming the hat frame.

In case it is desired to copy a pattern from the upper arms, upon thelower arms it is obvious that the upper set of downward depending armsare adjusted and then the hat formed thereon. The lower set of upwardlyextending arms are then brought into play and adjusted with its arms incorresponding position and then said lower set of arms may be removed.
